Nice so far!
You mentioned the belt rides up and it looked like it did in one direction and
then down in the other.
Do you think that's because the center pivot isn't well supported until you
install the pilot

How odd that the encoder manufacturer thinks that encoders are better :-)

Hopefully I'll get into a big cycloidal drive for my Cnc mill soon all out
of steel.
I was thinking of making it 300mm dia maybe.
I think most 5axis Cnc Mills use cycloidal drives if they don't just have
big direct drive servos.

I agree. Rather a nothing video. Took about 30 seconds to view it skipping
past the "these are screws in my hand" parts. And clicking on the x in the
advertising that kept popping up.
I too would like to build a robot arm to replace the Radio Shack Armatron I
bought while on holidays in

The Youtuber is just making stuff to show on Youtube. If he had a specific
use-case, then he would have to choose the system. Cycloidic drive can be
back driven and have a lower reduction. If you need that, you need that.
Harmonics can't be back driven and can have 100:1 reduction. The two are
Interesting video, and also interesting that the guy has
abandoned the harmonic drive in favor of cycloidal
drive.

To add one more idea to the long-running conversation of how to build a
harmonic reduction drive. Here is a working prototype that looks like the
flex-cup solution is solved. This could work for many years. But the
video shows only the idea and a prototype. I would not make this one but

Resolution is hard to quantify, as they are analogue devices, so the
accuracy is dependent on the measurement device, not the sensor.

1.Does this calculation make sense?

2. And if the gear ratio is made 1:5 ?
